The common wasp (Paravespula vulgaris) have black and yellow stripes and grow about 2 cm long. The common wasp can be identified from the vertical line on its head shield. The common wasp's body is pointed. Its yellow colouring is not very vivid. Wasps live in nests made of a paper-like mass. The nests are only used for a year, and most of the insects die in October. Only the queens can survive through the winter, and this is why wasps are rare in spring. Most of the queen's eggs develop into worker wasps, which can then become real pests in the late summer and autumn. It is important to realise that wasps themselves also catch plenty of insects, in particular harmful ones, and feed them to their larvae. A wasp colony can destroy up to two kilograms of insects per day. Nevertheless in autumn the community has already broken down. The wasps have only themselves to consider, there are no larvae, and their preferred food is carbohydrates. Wasps can cause very painful stings that stay swollen for a long time and itch badly.
Preventive measures and controls
- Do not leave food uncovered
- Never interfere with wasp nests, this is a job for a professional
- Use insecticides against individual wasps
